]Well, the so-called “ear nubs” are a part of the head-dress females wear, not a part of a twi’lek’s anatomy. They do have actual ears, even the females. To make them though, I’d suggest starting with a hemisphere instead of a cone then taper the sides of the hemisphere until it forms a rounded cone shape and attach it to your head-dress.
I’m sorry, but my inner fanboy side cannot let you say such things.
According to Wookieepedia, all male twi’leks have human ears, while some of the females have human ears, and others the ear nubs. Since wookieepedia is not the absolute reference, let’s check the facts:
- Movie-wise, all males seems to have human ears (Bib Fortuna being the most notable and almost the only example)
- The expanded universe (now reclassified as “Legends” seems to follow theses rules, I could only find one male twi’leks having clearly “ear nubs”, an unnamed Twi’lek pirate appearing in a single “the clone wars” comic. I’m gonna say it was more of a mistake from the illustrator than a genuine depiction of a male twi’lek:
- Movie-wise, since the lekkus are a movie prop, they most of the time depicted twi’leks wearing headbands so the transition between the actor with makeup and the lekkus props would remain unnoticed. Same goes with the ears: they either wear ear covers, or you see the “ear nubs” protruding from the prop.
Here are the two categories:
Full ear covers
Lyn Me have ear covers, which simply cover her ears, so I would be tempted to say she have human ears, as ear nubs are protruding much more
Ayy Vida (here on a behind-the-scenes picture) have large ear covers, so it is impossible to determine her ears shape
Oola is the most popular female twi’lek of the Original Trilogy, and have large ear covers that are hinting that her ears are massive, and therefore most likely ear nubs.
“Ear nubs” emerging from the headpiece
Most of the twi’leks shown in the episodes I-III have ear nubs visible, and with the very same hue as their skin:
- The Expanded Universe shows female twi’leks with either normal ears, or the ear nubs clearly being part of their anatomy:
But I do agree, your method is perfect for making ear nubs when they’re attached to the earpiece.
